An unwelcome guest at the nest

The osprey eyrie is mostly a place of gentle activity at this time of year, with one of the parents undertaking incubation of the eggs and then swapping over to give the other bird a break. There was a bit of a drama witnessed on camera on Tuesday 13th at around 2pm though, when the peaceful scene was interrupted by the unwelcome presence of an intruder osprey.

The female had been peacefully incubating the eggs and the male bird (white leg SS), was away from the territory, presumably hunting, when suddenly we could see a large shadow flying overhead. The female became quite agitated and began alarm calling and another osprey touched down briefly, before alighting away from the nest. This happened three times and the female was very upset. With her own partner away, she could not move from the eggs and just sat tight, calling out in alarm. We were able to record the action from the live camera and then take a still picture, capturing the briefest moment, when the intruder launched from the side perch on the nest. We can clearly see that this bird does not have a Darvic ring or BTO ring on its legs and so is not our male bird and is an unknown visitor. At this late stage into the incubation, we can speculate that it is a bird looking for a territory and nest site. It could even be a bird which has a nest site and is just being bold and mischievous checking out the neighbours!

We are looking forward to seeing the arrival of the chicks when they hatch at the end of May to the beginning of June.

The lonesome heron chick at Kailzie has grown so much that the parents are confident to leave it alone for longer periods. The youngster is big enough to hopefully defend itself against any predatory attack from crows.

The blue tit continues to incubate nine eggs at Kailzie and at Glentress Wild Watch, the jackdaws have three chicks hatched and two eggs unhatched.

The bees are very settled into their new home at Glentress and they are, quite simply, fascinating to watch.
